The embryonic stem in a seed is called thea. radicle.
b. hypocotyl.
c. seed coat.
d. endosperm.

Answers

Answer 1
Answer: the embryonic stem in a seed is the plumule.

it grows out of the hypocotyl, which that itself grows out of the radical, which is attached to the microphyl, feeds on the cotyledon, is fertilized by the endosperm, and is all protected by a hard seed coat :)

Bacteria with the ability to break down certain types of plastic are placed with colony for E. coli gain the ability to break down plastic as well. What inference can be drawn about the nature of plasmids from observation

Answers

Answer: Plasmid transfer occurs between the two colonies of bacteria and some of the E. coli gain the ability to break down plastic as well. What inference can be drawn about the nature of plasmids from this observation? Plasmids are nucleic acids which can pass on traits.

WILL MARK BRAINLIEST!!!! Can someone help me wit dis question? Summarize in 2-3 sentences the process of photosynthesis

Answers

Answer:

Photosynthesis is a chemical reaction where plants take in carbon dioxide (CO2) and water (H2O) through its stomata. With the help of sunlight and chlorophyll, which is found in its chloroplast, it is used to produce glucose (C6H12O6) and oxygen (O2). It converts light energy (sunlight) to chemical energy.

Explanation:

Answer:

please mark me brainlest!!

Explanation:

photosynthesis, plants take in carbon dioxide  and water from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and conversion of CO2 into carbohydrates (carbon fixation).

A scientist wants to examine living cells lining the respiratory tract to determine how the cells use tiny hairs to move dirt and mucus away from the lungs. Which of the following instruments would be best, and why?a. a scanning electron microscope, because it can be used to observe whole cells without slicing them
b. a transmission electron microscope, because it has high resolution

Answers


THE Answer Is B.I want to say because you going to need a high resolution but that's just what I want to say

Final answer:

A scanning electron microscope would be the best choice for a scientist examining the living cells lining the respiratory tract. This is due to its capability of scanning the surface of the whole cells, which is essential to properly observe the tiny hairs on these cells that move dirt and mucus away from the lungs.

Explanation:

To explore living cells lining the respiratory tract, the best instrument would likely be a scanning electron microscope (SEM). While both SEM and transmission electron microscopes provide high-resolution images, a key difference is how they interact with the specimen. The SEM scans the surface of whole cells, making it ideal for observing the tiny hairs, or cilia, on the cells of the respiratory tract. These tiny hairs move in coordinated waves, pushing mucus and trapped particles out of our lungs. This process can be best observed on the whole cell surface, which is why SEM would be preferred.

Animals can communicate by _____.making nosies
making gestures
phyisical contact
using scent or odors

Answers

Answer: making noises

Animals can communicate by making noises. The noises made by an animal is a form of communication in which only animals understand. This is a way of informing other animals of what a certain animal has discovered. 
i would making noises(A), why?
Cuz' we do not understand their language, but they actually do talk.
Our ears are just closed from understanding there language.
Also, look at the fish, only after people have created a microphone thing, then only at that point we know now, that fish make noises, and our ears were closed!!! only after the scientists made the thing, then only we now know that there are noises in the water.
Hope that this would help you! =)

A pine tree is a _____.
-bryophyte
-angiosperm
-gymnosperm
-fern

Answers

A pine tree is a gymnosperm. Gymnosperms are taxonomic class that will include plants whose seeds are not enclosed in an ovule (like a pine cone). These are often referred to as softwoods. Gymnosperms are seed-bearing vascular plants, such as ginkgo, yews, cycads, and conifers. (Conifers are the higher classification of a pine tree)
